A remote visualization system is proposed for the visualization of financial trading so as to provide a financial engineer at a remote site with the necessary decision support. The need to apply remote visualization to such a system is required because of the increasing need for an Internet based collaborative computational environment. By using such a proposed system, it is hoped that traders would then be able to gain an advantage over others.

Recently, the first in a series of planned comprehension experiments was performed to measure the effect of the control structure diagram (CSD) on program comprehensibility. Upper-division computer science students were asked to respond to questions regarding the structure and execution of a source code module written in Java. Statistical analysis of the data collected from this experiment revealed that the CSD was highly significant in enhancing the subjects' performance in this program comprehension task. The results of this initial experiment along with the planned follow-on experiments promise to shed light on fundamental questions regarding the effect of software visualizations on program comprehensibility.

Java has reinvigorated the debate on the `best' language to use for CS1. Much of the controversy centers on the goals of CS1, specific language constructs that either hinder or support the first formal introduction to programming, and, even, `real-world' relevance. Missing from typical discussions is the effect of the language choice in CS1 on CS2 and subsequent courses in the CS curriculum. In all such dialogues, it is important to note the characteristics of the department at hand. While many programs can afford to choose a language (such as Scheme) purely for pedagogical reasons, others (if not most), due to pressure from students, industry, advisory boards, select a language with some market appeal. Small departments that serve students who expect an immediate transition to a professional job typically choose a traditional procedural language like C, Pascal, Modula-2, or a popular OO language like C++, Java, Ada95, or Visual Basic. Hence, we focus here on the choice of one of these languages, and the resulting effects on students' progression in the CS curriculum.

We have developed a new, robust clustering algorithm, Self-Splitting Competitive Learning (SSCL). It has shown great abilities in detecting not only isolated clusters, but overlapped clusters, curves and spherical shells. We apply SSCL to quantization of color images. The clustering algorithm iteratively partitions the color space into natural clusters without a prior information on the number of clusters. The algorithm starts with only a single color prototype and adaptively splits it into multiple prototypes during the learning process based on a split validity measure. It is able to discover all natural groups; each is associated with a color prototype. The experimental results show remarkably better performance as compared to several other existing clustering algorithms.

Recently one of the first in a series of planned comprehension experiments was performed to measure the effect of the control structure diagram (CSD), reverse engineered from source code, on program comprehensibility. computer science students in an object oriented programming course were asked to respond to questions regarding the structure and execution of a source code module written in Java. Statistical analysis of the data collected from this experiment revealed that the CSD was highly significant in enhancing the subjects' performance in this program comprehension task. The results of this initial experiment along with the planned follow-on experiments promise to shed light on fundamental questions regarding the effect of software visualizations on program comprehensibility.
